Batch Update methods: POST HTTP verb

This rule enforces that all BatchUpdate RPCs use the POST HTTP verb, as mandated in AIP-234.

Details

This rule looks at any RPCs with the name beginning with BatchUpdate, and complains if the HTTP verb is anything other than POST.

Examples

Incorrect code for this rule:

// Incorrect.
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BatchUpdateBooksResponse) {
  option (google.api.http) = {
    get: "/v1/{parent=publishers/*}/books:batchUpdate" // Should be `post:`.
    body: "*"
  };
}

Correct code for this rule:

// Correct.
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BatchUpdateBooksResponse) {
  option (google.api.http) = {
    post: "/v1/{parent=publishers/*}/books:batchUpdate"
    body: "*"
  };
}

Disabling

If you need to violate this rule, use a leading comment above the method. Remember to also include an aip.dev/not-precedent comment explaining why.

// (-- api-linter: core::0234::http-method=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BatchUpdateBooksResponse) {
  option (google.api.http) = {
    get: "/v1/{parent=publishers/*}/books:batchUpdate" // Should be `post:`.
    body: "*"
  };
}

If you need to violate this rule for an entire file, place the comment at the top of the file.
